matically transferring water from a boiler.

'to a filter in the coffee pot, and of automatically removing saidboiler from over the lamp, and placing said coifee pot over said lamp;and to suchends my invention consists in the automatic coffee potvhereinafter specified.

In the accompanying drawings 1 have illustrated one embodiment of my1nvention, but such embodiment is to be regarded as typical only of manypossible embodiments.

Figure 1 is a side elevation of one embodiment of'my invention; Fig. isa vertical sectional view through the boiler and lamp support; Fig. '3is an end elevation showing the coifee pot in section; Fig. 4' is a topplan view the coffee pot and boiler being removed; and Figs. 5 and 6 arerespectively a side elevation and a front elevation of the supportinpost and sleeve andthe parts immediate y carried thereby.

In such embodiment I khave provideda base 1, having thereon alamp-support 2, in which rests a lamp 3, such, or instance, as analcohol lamp. Thel support 2 carries a bracket 4, uponS which is hingedacover 5, that is adapted to fit over the lamp. The said cover isprovided with an opening 6, through which the flame may rise. A valve isprovided for exposing'or closing the said opening, and such valve, asillustrated,` consists of a disk 7 of suitable size for covering thesaid o ening, said disk being mounted on the en also preferably providestops 10 and 11, formed by the bent-up ends of a stri that is secured inthe said cover arms, w ich sto s limit the extreme movements of the sailever. A post 13 is mounted u on the said base and a sleeve 14 upon thesaid post. rlhe lower edge l5 of said sleeve is formed into a spiral orscrew,fwh,ieh is ada ted to rest upon a stop 16 fastened upon t e saidof a lever 8, that is, fulcrumed' .as upon a screw 9 on`the said coverarm. I

' post, and preferably having an upper surface inclined to correspondwith the incline of the said screw, in such a manner that as the sleevedescends upon the post, as later described, its inclined surface act-ingupon the said stop, tends toturn the sleeve and the parts carriedthereon. The said sleeve is provided Kwith a bracket 17, or other formof support, which, in the 'present instance, carries screws '18, uponwhich the coffee-pot proper is mounted, as hereinafter described. Thesaid bracket also has ears, between which is fulcrumed a lever l19. Thesaid lever has a vertical arm 20, upon which is mounted a hook 21, thatis adapted to eng'age a pin 22, mounted in or upon the vertical post.The hook and pin are correspondingly beveled, so that as the hookapproaches the pin, in the rotation of the sleeve upon the post, itsbeveled face shall ride over the beveled face'of the pin, and itsvertical face engage the verticalface on the far side of the pin. Uponthe said screws is mounted a combined coffee-pot and boiler, consistingof a coffee-pot 23 and a boiler 24, connected as by bars 25, the saidbars having notches 26 that are adapted to lit over the said screws, soas to support and fulerum the said combined structure on said screws.The coffee-pot and boiler are also connected preferably at other pointsby braces, so that they are rigidly fastened together. may be closedsubstantially steam-tight by a cover, the latter being preferablyscrewed on to the can. A pipe.27 extends into the said can and nearly tothe bottom thereof, and enters the can 28 of the coffee-pot near the topthereof. A small vent is preferably provided in the boiler cover, so asto permit the escape of air until steam is formed.

Within the coifee-pot are provided any devices which will serve to makecoffee, but preferably some form of lter that will hold the coffee wellabove the bottom of the coffee-pot, so thatl water may be filteredthrough the coffee and pass entirely below the same. The said filter inthe present instance consists of a cup 29, having a flange that is adated to rest upon lugs 30, formed A sieve 31 closes the lower end of thecup, and there is preferably also a plate 32, which has perforationssmall enough to prevent most of the coifee grounds from passingtherethrough.

In the lower end of the coifee-pot is a The boiler consists of a canthat spigot 33, from which the'made coffee can be drawn.

The rear end of the leveris adapted to support the boiler,"and the frontend of the the lever, which engages the bottom of the the upper surfaceof the water,wil1 force waboiler,` and inside of a flange lformedthereon.

In the operation of my coffee-pot, the

combined coffee-pot and boiler are turned.

until the boiler is over the lamp, in which position the hook will haveengaged its stud, and the sleeve be thus locked in its highest position.The water in the boiler also will keep the rear end of the lever tippeddown, and thus keep the hook in engagement with the stud. The lamp beinglighted and regulated, will heat the boiler and gradually form steamtherein. The steam pressing on ter through the pipe and over into thecup within the coffee-pot. There the water Will filter through thecoii'ee Within the said cup,

and pass to the bottom of the coffee-pot ready touse as coffee. Whenalllthe water in the boiler has been forced over into the coffee-pot bythe action of the steam, the center of gravity of the combined coEee-potand vboiler will have changedl from the rear side of the lever to theforward side thereof,

andthe coffeeot'will tip down, raising the boiler and raising the rearend of the lever, and disengagin the hook from its pin.

The weight of t e parts will ythen cause vthe screw surface on thesleeve to slide down on the beveled lug upon which it rests, thusturning the sleeve until the boiler has been removed from over the lamp,and the coffeepot has been swung over the lamp. In this position themade coffee is kept heated by the lamp.

It will be observed that the action of my coffee-pot is automatic, andthat it is not necessary to Watch it to see when the coffee iscompleted, and to prevent burning the boiler by the continued"application'of heat after it is empty, nor to take any trouble to seethat the coffee is kept hot.

Itis obvious that various changes can be made in the aboveillustrated-construction which will embody the spirit of my invention,and I desire not Ato be limited beyond the'intendment of my claims, orthe necessary requirements of the prior art.

`1. A coffee-pot, comprising a coffee-making device, consisting of acoffee-pot and a boiler, a connection therebetween for transferringwater, a'lamp, and means for automatically removing said boiler fromsaid lamp, andj'applying said lamp tosaid coffeecoffee-pot above thebottom thereof, a lamp, and means for holding said boiler over said lampuntil the Water has been transferred to the coffee-pot, and for thenremoving said boiler from said lamp and bringing said.
